Antioxidant for polyurethane

The antioxidant for polyurethane operates through radical-trapping and peroxide decomposition mechanisms, protecting PU polymers from chain scission and embrittlement. It can be used in combination with UV stabilizers for enhanced aging resistance. Compatible with ether and ester PU systems, it maintains clarity, flexibility, and processing stability under thermal stress. Ideal for molded elastomers, coatings, and sealants.
